description
Kalanchoe dinklagei forms small trees that reach heights of growth of 8 to 10 meters and which branch out from the base. Their thick shoots are initially thickly covered with grayish or reddish brown hairs , which later give way to a grayish bark. The thick, strong and fleshy leaves are green-white to whitish silver and wrapped with star-shaped hair. The 1 to 2 centimeter long petiole is broadened and furrowed on top. The egg-shaped, egg-shaped-spatulate leaf blade is 3 to 6 inches long and 2.5 to 4 inches wide. It is blunt at the tip, rounded to slightly truncated and narrowed at the base. The leaf margin is entire. Young leaves are sometimes ovate, oblong triangular, elliptical to oblong with wavy to rough toothed edges.
The inflorescence is a dense, many-flowered thyrse of up to 30 centimeters in length. The hairy inflorescence stalk is 20 centimeters long. The upright to spreading, yellow-green to whitish flowers sit on fleshy, long-haired, about 3 millimeter long pedicels . The pale green, densely long-haired calyx tube is tubular, 3 to 4 millimeters long and ends in triangular lobes that are 5 to 8 millimeters long and about 3 millimeters wide. The densely long-haired (star-shaped and sometimes glandular hair), corolla is green-yellow, whitish-yellow, pink. The cylindrical, 10 to 15 millimeter long corolla tube has lanceolate and somewhat spreading tips that are 2.5 to 3.5 millimeters long and 1 to 2 millimeters wide. The stamens are attached above the center of the corolla tube and protrude slightly from the corolla tube. The egg-shaped anthers are 0.5 to 0.8 millimeters in size. The rectangular nectar flakes are about 0.8 millimeters long and 0.6 millimeters wide. The elongate fruit leaf is 8 to 10 millimeters, of the stylus 5 to 6 millimeters long.
